Hi, have been trying to read the request body in my module, using the  
information I have gotten from this forum and some blogs and basically  
came  
up with the following functions  
as can be seen in this post [Reading request body in a module](http://forum.nginx.org/read.php?11,245953).  
The  
problem is that the request\_body.bufs seem to contain no data.

If I check the request body with the following conf:

```
log_format my_tracking $request_body;

   location /dd {
      access_log logs/postdata.log my_tracking;
      proxy_pass http://127.0.0.1:8081/temp_service;
    }

    location /demo {
      access_log logs/postdata.log my_tracking;
      demo;
    }

```

I get the request\_boody logged in the first /dd post request but in the  
second /demo I do not get anything logged if I post data  
Use the following command the trying it out: curl -v --request POST -d  
“a=b” [http://localhost:8080/dd](http://localhost:8080/dd)  
Anyone that have an idea what can be wrong?

Best Regards  
Christer
